  • Method of manufacturing bulk single crystal of gallium nitride
    Publication number: 20040244680
    Abstract: The present invention provides a process for forming a bulk monocrystalline gallium nitride by using supercritical ammonia. The process comprises the steps of forming a supercritical solvent containing ion or ions of alkali metals in an autoclave; and dissolving a monocrystalline gallium nitride prepared by flux methods as a feedstock in this supercritical solvent to form a supercritical solution, and simultaneously or separately recrystallizing gallium nitride on the face of a seed.
